RedDwarf: Where does your rhythm come from, anyway? He has a similar method
Your technique is one of vulnerability and trust. Breathe just right, lie to your heart and limbic system that this dark world is a safe one. Lie hard enough and it'll become true. Know, even when it's wrong, that your friends will come through and keep you safe, that you can trust them to the end of the galaxy. The knowledge steadies the hand, quickens the trigger-finger.
His, too. He has that same trust, that same vulnerability.
It's all about the crew. It's always, always been about the crew.
